To all whom it may concern:

Be it known that i, RUnoLr A. Kownnsnr, a citizen of the United States, residing at \Voonsocket, in the county of Proyidence and State of Rhode Island, have 1nvented. new and useful Improvements in lVaterboards for Vvringing Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in water boards for wringing machines, and the primary ObJGCl) of the invention is to provide a water or drain board which is of strong and durable construction and which is formed of a single piece of material that is strengthened or reinforced at its sides and ends and in which the sides are provided with water directing or guiding members.

A further object of the invention is to provide a drain board which is of simple and economical construction, and which can be easily and quickly made and at the same time provides a staunch and lasting structure.

Further and other objects will be later set forth and manifested in the course of the following description.

In the drawings:

Figure 1, is a side elevation of the invention applied to a wringer;

Figure 2 is a central longitudinal sect-10nal view of the board;

Figure 3 is an enlarged detail fragmeritary view showing the manner of forming the sides;

Figure 4 is a perspective View of a modified form;

Figure 5 is a fragmentary perspective View showing one of the corners of the board prior to shaping and forming same into its finished form; and

Figure 6 is a fragmentary perspective view showing a modified form of the invention.

In proceeding in accordance with the present invention, the board is preferably made of a sheet of aluminum, though other sheet metals can be employed equally as well. The sheet metal is formed to provide a flat body 1, the ends of which are rolled or curled downwardly as depicted at 2 "to form tubular ends for the board. in order to provide side flanges or guides for the board, each side of the sheet metal is first bent upwardly at 3, then doubled over and bent outwardly upon itself at at and extended to project below the body and finally again doubled over and bent inwardly upon itself at 5, with the free edge 6 of the side preferably abutting the under face of the body 1 so as to receive support from the body 1 as depicted in Figure 3 As illustrated in Figure 5, the parts 5 may be formed with lugs or ears 7 which extend at right angles thereto arid which underlap and are soldered or brazed or otherwise rigidly secured to the body 1. If desired, the body 1 may be out at an incline at its corners as indicated at 8 and the ends of the sides of the board thus have converging ends which act to direct the water toward the center of the board, or as illustrated in Figure 6, the sides of the board may be straight throughout and in this instance, the ears or lugs 7 may be dispensed with and the ends of the tubes 2 then left fiat and abutted against the sides and soldered or brazed thereto, to thus form a solid and strong structure. Slots 10 are formed in each of the sides of the board so that the latter may be used either on the right or left hand side of the wringer by use of suitable attaching devices 11,

From the foregoing it will be seen that the sides of the board are of double thickness and that the tubes 2 reinforce the ends and that since the ends of the tubes 2 abut the sides, the two mutually reinforce and brace or strengthen each other.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a drain board, a sheet metal plate having its ends shaped to form tubes and having its side marginal portions extended upwardly and then downwardly and again extended upwardly to form parts of double thickness both above and below the body of the plate, the edges of the side marginal portions having integral ears secured to and beneath the body of the plate and the ends of the tubes abutting portions of the side marginal portions.

2. In a drain board, a sheet metal plate having its ends shaped to form tubes and having its side marginal portions extended upwardly and then downwardly and again extended upwardly to form parts of double W the edges of the side marglnal portions having integral ears secured to the body 01 the plate.

y In testimony Where/oil have signed my name to this specification in the presence of two subscribing witnesses.
